Document Summary

Acidosis: blood ph shifts to acidic side, from an excess of h2co3 or a reduced amount of bicarbonate. Alkalosis: blood ph shifts to basic side, from a decrease in h2co3, orfrom an excess of bicarbonate. Metabolic: disturbance lies in bicarbonate member of the buffer pair. Excretory duct system: ureter: conveys urine into bladder by peristalsis, renal pelvis: expanded upper portion of ureter, major calyces: subdivisions of renal pelvis, minor calyces: subdivisions of major calyces into which renal papillae discharge. Bladder: stores urine: discharges urine into urethra during voiding, anatomic configuration of bladder and ureters normally prevents reflux of urine into ureters. Urethra: conveys urine from the bladder for excretion. Nephrons is the basic structural and functional unit consists of glomerulus and renal tubule. Glomerulus (bowman"s capsule) tuft/mass of capillaries supplied by an afferent glomerular arteriole that recombine into an efferent glomerular: mesangial cells: contractile phagocytic cells that hold the capillary tuft together; regulate caliber of capillaries affecting filtration rate.
